Is this really the final piece of the jigsaw for Liverpool?
There is a lot of talk that this is a gamble for Liverpool. In some respects it is, Robbie Keane is 28, there's no re-sale value and he will have no time to bed in.

But Liverpool are hoping they have bought proven quality and they will want an immediate return on their investment. Keane has scored a lot of goals for Tottenham but the demands of a top four club are different, he will need to produce a level of consistency that he hasn't had to before and Benitez will hope he is able to do that.

There's a lot of encouraging signs and I certainly think he's going to give Liverpool a lot more options up front. Benitez has generally favoured younger players, so in some ways this is a change of policy because he has realised that sometimes you need to buy the finished product.

Does this signing bring Liverpool any closer to winning the Premier League?
I think if Keane is a success then it absolutely will. You look at the strength of Chelsea and Manchester United and it's clear they are going to take some overhauling.

But if Torres and Keane can click they are going to be a pretty potent strike force and it will certainly ask a lot more questions of defences. Liverpool have never had a shortage of very capable players but Benitez himself has admitted they have been over reliant on Gerrard and Torres so it just brings an added dimension.

If Keane scores 20 goals, Torres gets 30 and Gerrard gets 20 Liverpool are going to be an altogether different proposition in terms of the title.

How do you see him fitting in to the team?
Benitez has got a couple of options. He could either go 4-4-2 and play Keane and Torres up top, which might dictate that Gerrard is pushed back on to the right. Or he could go 4-2-3-1, as he did last season, with Torres up top on his own and Keane and Kuyt out wide with Gerrard through the middle. Although Keane has the ability to play in any of forward positions.

Will Keane feel under more pressure to deliver at Liverpool?
I don't think the fee or even the fact he's wearing the No 7 shirt will be a burden for him.

I just think it will be interesting to see whether he can produce top form regularly. Spurs are obviously one of the clubs who are moving closer to the top four - but this move is a significant step up and presents a whole new series of demands.

It will be interesting to see how playing in the Champions League regularly affects his form in the league with the extra number of high-pressure games. But he's a player with no shortage of confidence.

Do you think this deal ends Liverpool's hopes of signing Gareth Barry?
No I don't, they are still hopeful that they will sign him but that is now dependent on Benitez offloading other players.

The principle one is Xabi Alonso, if they can offload him they will certainly make another bid for Barry. The alternative is offloading Voronin, Pennant and Arbeloa, who could return to Spain.

But whether Benitez would want to bring Barry on board without getting rid of Alonso and therefore still have a surplus of high-quality central midfield players I don't know. That in itself would create different problems.
